Current OutputField Transmitters Note 1. All 2100-A16 analogue inputs are

differential. Maximum peak voltagebetween any 2 inputs is 18V.In example 2, the peak voltage iscalculated by multiplying the max mA outof any transmitter, by the sum of theresistances in the transmitter loop, thenadding any common peak voltages.

eg: (refer to Connection Example 2)If the transmitter has a 35mA max, the2100A16 has 25Ω input resistance; and ifa chart recorder has 250Ω input resistance:There is a 2V peak common voltage.

=> 35mA x (25Ω + 250Ω) + 2V = 11.63V peak.This is fine, as it is less than 18V.

Note 2. For mA inputs a jumper must be installed.J1 for channel 1, J2 for channel 2, etc. Thejumpers are located directly behind the 3terminals for each respective channel. Theycan be installed without removing the cover.

Note 3. Inputs can be used as digital inputs forsensing a clean, voltage free, field contact.

Note 4. All cables must be screened, and thescreens earthed at one end only.

Note 5. Voltage free contact values must be broughtin through ‘tags’ in the Scada Software.

Note 1. All thermocouple inputs are differential. Maximum peakvoltage between any 2 inputs is 18V.

Note 2. It is recommended that the thermocouples be isolated fromeach other and earth. Isolated junction, mineral insulatedthermocouples are recommended.

Note 3. For accurate thermocouple measurement, especially low temp:*The cover must be fitted.*Avoid drafts and temperature differences across terminals.*Once installation is complete, close the cabinet door and allow the cabinet to reach equilibrium. This may take several hours.*Place all the thermocouple probes into a calibrated thermalbath at the temperature of interest. Any errors can be zeroedout in software.

Note 4. All thermocouples are referenced to the on board cold junctioncompensation temperature sensor, located behind terminal 13.Alternatively one of inputs 1 to 8 can be selected in theScada software as an RTD CJC for inputs 1 to 8, and one ofinputs 9 to 16 can be selected in the Scada software as anRTD CJC for inputs 9 to 16.

Note 5. All cables must be screened, and the screens earthed atone end only.

Note 1. All RTD inputs are single ended. ie all the2nd ‘B’ terminals are internally connected.

Note 2. It is recommended that the RTDs be isolatedfrom each other and earth.


Note 4. All RTD cables must be screened, and thescreens earthed at one end only. All the threewires must be the same resistance. (ie. thesame type and size.) Refer to ‘Wiring andInstallation’ for recommended types.

Note 5. To minimise lead resistance errors, 3 wireRTDs should be used. If 2 wire RTDs areused small offset errors can be compensatedfor in software.

Note 6. For voltage free contacts use RTD6 0 to 850for pseudo digital input in the Scada Software.

* Refer to Wiring & Installation.

Once the 2100-A16 outstation is connected to the data hi-way, apply the power. Refer ‘2100-A16 Wiring & Installation’.2. If the system is already running, close the Scada down. Start the ‘Setup Manager’.3. Select ‘Recorder Setup’, or ‘Tag Setup’.4. Select ’Program Address’. (Located in ‘Station Programming Panel’, at the bottom right of the window.5. Enter the 2100-A16 serial number. (Written both on the 2100-A16 cover, and on the circuit board behind the power

terminals.) Then enter the desired station number.6. Select ‘Program’. The station number will now be stored in 2100-A16 permanent memory.7. A new station number will be created on the outstation map. This is ready for connection to tags or lines.

2100-A16 Station Software Programming.*Requires Microscan Version 4.02 onwards.1. If the system is already running, close the Scada down. Start the ‘Setup Manager’.2. Select ‘Recorder Setup’, or ‘Tag Setup’.3. Move to the required station number, using ‘next’ or ‘prev’ buttons.4. Select ‘Program Setup’. The serial number of the 2100-A16 will be recalled automatically. The software recalls

the settings from the outstation, and displays them in the dialogue box.5. Enter the required options and select ‘Program’ to write the data to the station.

Section D:Connecting to a PLC as an Intelligent Multiplexer.

To set up the 2100-A16 as an intelligent multipexer a free software CD is available from Intech Instruments. Place theCD into the drive and follow the instructions. The analogue output mode must be selected as either Mode 3 or Mode 4.This is set in the Station Advanced Dialog Box ‘AO 1 & AO 2 button’.*Requires Station Software 024 onwards. Fordetailed programming info, refer to ‘Programming 2100-Series Remote Station’ in the Microscan Manual.

Note 1. AO 1 = retransmission of input process value 1~16.AO 2 = retransmission of controller setpoints 1~16.

Note 2. The input and output always share the same range. Eg. If input1 is ranged 0~100C and retransmission channel 1 is selectedon DI 1 ~ 4, then AO 1 & AO 2 are both transmitted as 4~20mA(or 0~10V etc) = 0~100C. Similarly if input 2 is ranged for0~250C, then AO 1 & AO 2 are transmitted as 0~250C.

Notes 3 If AO 1 process value or AO 2 setpoint are transmitted toan indicator, then all the inputs must be ranged the same,unless the indicator is ranged to 0~100%.

Note 4 In the PLC RTX modes, AO 2 always retransmits the controllersetpoint regardless if the controller is enabled or not.

Note 5. The PLC RTX modes can operate simultaneously with theScada COMMS, allowing a PLC to read back data that theScada will be showing.

Note 6. Digital inputs and digital outputs are not available in this mode.

Section E:Connecting Using Communication Protocol.

‘Read Only From 2100-A16’ and ‘Read and Write to 2100-A16’ Protocols are both available from Intech Instruments in‘WORD’ format, free of charge.

Read Message is OMRON compatible read DM area. 2100-A16 protocol is the protocol used by Microscan to accessdata in stations. Uses ASCII messages and IEEE 754 to represent floating point values.

Section F:2100-A16 Wiring and Installation.THE 2100-A16 IS TO BE INSTALLED AND SERVICED BY SERVICE PERSONNEL ONLY. NO OPERATOR / USER SERVICEABLE PARTS.Important: Where ground loops, excessive noise or excessive voltage is present on or between analogue inputs,suitable isolating transmitters are required, otherwise errors in signal readings will occur. If the analogue output is usedinto a non-isolated other unit, it is recommended that a suitable isolating transmitter be used on the analogue output.

2100-A16 Mounting.* Also refer to Connection Diagrams and Notes.(1) Mount in a clean environment in an electrical cabinet on DIN or EN mounting rail.(2) Do not subject to vibration or excess temperature or humidity variations.(3) Avoid mounting in cabinets with power control equipment.(4) To maintain compliance with the EMC Directives the 2100-A16 is to be mounted in a fully enclosed steel fire

cabinet. The cabinet must be properly earthed, with appropriate input / output entry points and cabling.

Power Supply Wiring.(1) A readily accessible disconnect device and overcurrent device must be incorporated in the power supply wiring.(2) Any 2100-R connected to the 2100-A16, must share the same disconnect device and overcurrent device(2) For power supply, connect Phase (or +Ve) to terminal 82, Neutral (or -Ve) to 81, and Earth to 80. To ensure

compliance to CE Safety requirements, the orange terminal insulators must be fitted to ALL mains terminals afterwiring is completed. (ie. terminals 82, 81 and 80.) For Non Hazardous Voltage power supplies (not exceeding42.4Vpeak or 60Vdc) terminals 81 and 80 may be linked together, instead of connecting an earth.

RS422/485 Comms Cabling.NOTE: All cables are to be subject during manufacture to in-process spark testing @ 4kVrms. All cables are to betested between conductors and conductors to screen for 1min @ 1500Vrms.

(1) Use only low capacitance, twisted pair, overall screened data cable. The cable must equal or better thespecifications in the table on the following page.

(2) Minimum cable pairs: RS422 = 2. (Plus overall screen.) RS485 = 1. (Plus overall screen.)(3) Take care not to stress or damage cables during installation.(4) Total length of trunk line, including spurs, is not to exceed 1200m without isolating boosters.(5) Terminating resistors -1kΩ.(6) Cabling paths should avoid sources of radio frequency interferences such as fluorescent lights, variable speed

motor drives, welding equipment, radio transmitters, etc.(7) There should be a minimum of 200mm physical separation between power cables and data cables.(8) Data cables should not be exposed to excessive heat or moisture, and should not be buried directly in the ground

without protection.(9) Avoid powering a remote station or controller from the same power supply as a variable speed drive.

2100-A16 Wiring and Installation Cont inued.

Analogue Signal Wiring.(1) All signal cables should be good quality overall screened INSTRUMENTATION CABLE with the screen earthed at

one end only.(2) Signal cables should be laid a minimum distance of 300mm from any power cables.(3) For 2 wire current loops, 2 wire voltage signals or 2 wire current signals, Austral Standard Cables B5102ES is

recommended. For 3 wire transmitters and RTDs Austral Standard Cables B5103ES is recommended.(4) It is recommended that you do not ground analogue signals and use power supplies with ungrounded outputs.(5) Lightning arrestors should be used when there is a danger from this source.(6) Refer to diagrams for connection information.

RTDs.(1) Avoid locating the RTD where it will be in a direct flame.(2) Locate it where the average temperature will be measured. It should be representative of the mass.(3) Immerse the RTD far enough so that the measuring point is entirely in the temperature to be measured; nine to ten

times the diameter of the protection tube is recommended. Heat that is conducted away from the measuring pointcauses an error in reading.

Thermocouples.(1) Avoid locating the thermocouple where it will be in a direct flame.(2) Never insert a porcelain or refactory tube suddenly in a hot area. Pre-heat gradually while installing.(3) Locate it where the average temperature will be measured. It should be representative of the mass. If necessary use

several thermocouples to obtain the average temperature.(4) Immerse the thermocouple far enough so that the measuring junction is entirely in the temperature to be measured:

nine to ten times the diameter of the protection tube is recommended. Heat conducted away from the junction causesan error in reading.

5) If the thermocouple is mounted horizontally and the temperature is above the softening point of the tube, a supportshould be provided to prevent the tube sagging. Otherwise install the tube vertically.

((6) Keep the junction head and cold junction in the approximation of the ambient temperature. Especially in the NobleMetal Class.

(7) On open circuit thermocouples (T/C) floats to ambient ±10C typical. For upscale or downscale drive resistors mustbe fitted externally. Refer to ‘2100-A16 Input Connection Diagram Thermocouple Upscale (US) / Downscale(DS)Drive.’ If ground loops or excessive noise are present on the T/C inputs, or between T/C and other inputs, the readingsmay not be accurate, and an open circuit T/C may not drive as expected. In these situations an isolating transmittermust be used.

Thermocouple Extension Wire.(1) Use the correct thermocouple extension or compensation cable. i.e. Thermocouple type, insulation type, correct

colour coding.(2) It is recommended to install extension or compensation cable in a grounded conduit by themselves, or use overall

screened cable with the screen earthed at one end only. Never run electrical wires in the same conduit.(3) All wires that must be spliced should be soldered, or a proper thermocouple termination block used.(4) Lightning arrestors should be used if there is a chance from this source.

2100-A16 Commissioning .(1) Check that the 2100-A16 has been set up to the right input ranges, and that it’s new ranges have been checked.(2) Once the above conditions have been met, and the wiring checked, apply power to the 2100-A16, the loops, sensors,

2100-Rs and 2100-Ms. Allow a 5 minute warm-up period - longer for thermocouples - refer to Input ConnectionDiagram for Thermocouple Inputs, Note 3 & 4.

Note 1. There is a 15sec initialisation period when the 2100-A16 is powered up, before it will communicate.Note 2. For maximum accuracy allow a 6 hour warm up period.Note 3. If T/C upscale or downscale drive resistors have been fitted, check that each channel drives to the

desired level on open circuit.

(3) For Clock/Reset Channel Selection:Check that the red LEDs on the 2100-A16 and 2100-M are flashing. The LED next to the Clock terminal (62) shouldflash 16 times faster than the LED next to the Reset terminal (61). For each Clock or Reset pulse received therespective LED on the 2100-A16 and 2100-M will go from OFF to ON to OFF. If a Clock or Reset line is held high,the respective LED will remain ON. If a Clock or Reset line is held low, the respective LED will remain OFF.

(4) Take a reading of the value being measured on each channel, and ensure that this agrees with the level beingindicated by the Data Logger or PLC, for that channel. Adjust for any differences in the software of the system.

Note1. RTDs: A small error can occur due to differences in cable resistance in the RTD legs, and errors in the RTD itself.(Usually less than 0.5C). To check the variable being measured use a calibration standard RTD at the same immersiondepth. If the Zero error is large, the readings are fluctuating or a Zero error has suddenly appeared after the2100-A16 has been operating for some time, there could be an earth loop between two or more RTD sensors on the2100-A16 (or between 2100-Ms if connected). Disconnect each RTD sensor individually from the 2100-A16, and‘Megger’ the RTD by shorting all three wires together and testing from this point to earth. If a path to earth is foundrepair or replace the faulty RTD sensor or probe.

Warning : Do not ‘Megger’ the RTDs while connected to the 2100-A16. Damage to the 2100-A16 or 2100-M will result.

Note 2. Thermocouples: Due to the limits of error in a standard thermocouple probe, and standard extension wire andcompensating wire, an error can occur. For example in a type K thermocouple installation an error of 2.2C or 0.75%FSO can occur (whichever is greater). To check the temperature being measured use a calibration standardthermocouple at the same immersion depth.

2100-A16 Maintenance.Voltage and Current Inputs.(1) Repeat (4) of commissioning. Do it regularly - at least once every twelve months.

RTD Inputs.(1) Repeat (4) of commissioning. Do it regularly - at least once every six months.(3) Replace defective protection tubes - even if they look good they may not be air or gas tight.(4) Check cables entering the RTD sensor head.

Thermocouple Inputs.(1) Repeat (4) of commissioning. Do it regularly - at least once a month.(3) Replace defective protection tubes - even if they look good they may not be air or gas tight.(4) Check extension and compensating cable circuits.(5) Do not use the same chromel-alumel (Type K) thermocouple below 540C if it was used above 860C.
